Bike light charger! Technical question!

[Fatmat]

Hello, I have a One23 Extreme Bright 1000 bike like with battery pack and have lost the charger. I’ve searched google for the manual but can’t find anything! Does anyone have one that they can check what type of charger I need? Or know how to find out? Thanks

It'll just be a standard bike light 'charger' / psu.
Probably the 8.4V version but I also have lights that look identical and use a 4.2V charger.
Which is a pain as I had to able the battery packs as they look the same, just wired in a different pattern.

It may be best to buy new, if you LiIon pack has been left flat for a long time, it might be hard to bring it back up and probably had reduced capacity.
You only need new batteries and charger though. But newer lights might be cheaper and better anyway.
